The number of Hispanic students in the nation's public schools nearly doubled from 1990 to 2006, accounting for 60% of the total growth in public school enrollments over that period. Strong growth in Hispanic enrollment is expected to continue for decades, according to population projection by the U.S. Census Bureau. Using data from the 2006 American Community Survey (ACS), this report presents information on the demographic characteristics of Hispanic students in public schools, comparing Hispanic public school students with their non-Hispanic counterparts. Large sample sizes available in the ACS enable detailed comparison of Hispanic students across generational groups. Highlighted characteristics of Hispanic public school students include: (1) More than 80% of Hispanic public school students were born in the United States; (2) More than half of all Hispanic students are enrolled in public schools in Texas and California; (3) Foreign-born Hispanic students are more likely than native-born Hispanic students to live in "new" and "emerging" Hispanic states; (4) Hispanic kindergartners in public schools are overwhelmingly born in the U.S. (93%), compared with 86% of Hispanic students in grades 1 through 8 and 77% in high school; (5) Majority of Hispanic students are of Mexican origin, followed by Puerto Rican, Dominican, Salvadoran and Cuban; (6) Nearly three-in-five Hispanic students live in households with both of their parents compared with 69% of non-Hispanic white students and 30% of non-Hispanic black students; (7) More than seven-in-ten U.S. born Hispanic students of immigrant parents live with both parents; (8) 28% of Hispanic students live in poverty, compared with 16% of non-Hispanic students; (9) Foreign-born Hispanic students are more likely than their native-born counterparts to live in poverty; (10) 34% of Hispanic public school students have parents who have not completed high school, compare to 7% of non-Hispanic students; (11) 70% of Hispanic students speak a language other than English at home; (12) Almost 30% of Hispanic public school students report speaking only English at home, and an additional 52% of Hispanic public school students report speaking English "very well" ; (13) Nearly half of first-generation students speak English with difficulty, compared with 20% of second-generation students and 5% of the third-and-higher generations; and (14) Most Hispanic students live in households in which at least one household member over the age of 13 speaks only English in the home or speaks English very well. Two appendices are included: (1) Demographics of Public School Students; and (2) Generational Distribution of Hispanic Public School Students. (Contains 13 footnotes, 8 figures and 15 tables.)
